Title: A device for adjusting the die and mandrel in extrusion presses for non-cylindrical hollow profiles
IPC: B21C25/00
Filed: 1952-12-23
Abstract: 733,939. Extruding. SCHLOEMANN AKT.-GES. Dec. 23, 1952 [Jan. 10, 1952], No. 32555/52. Class 83 (4). A device for adjusting the die and mandrel on an extrusion press for extruding non-cylindrical hollow sections is characterized in that the mandrel is rotatable about a stationary axis to enable the non- cylindrical surfaces of the mandrel to be angularly adjusted into parallelism with the corresponding surfaces of the die. The extrusion press comprises a die 3 in a holder 2 which is slidable transversely to the direction of extrusion in a housing 1. The holder 2 has a bore 4 which may be used for accommodating a second die or for ejecting seized ingots by moving the bore into line with the axis of the press. The holder is movable along a lower guide-track formed by a wedge 20 which is longitudinally adjusted by a set-screw 21 for raising the holder for alignment purposes. A piston 22 exerts pressure on the holder and retains it firmly in position. Lateral movement of the holder is effected by hydraulic cylinders 25 and 26 and stops 24 limit said lateral movement. In front of the die holder is located a billet container 5. The hydraulic piston 7 of the press has a tubular extension 8 protruding through the closed end 9 of its cylinder 10 and the extension acts as a guide for the piston on the mandrel rod 11 which carries a mandrel 12 having a nose corresponding to the inner cross-section of the hollow section to be extruded, e.g. a square. The rear end of the mandrel rod is supported by a carrier 15 and the mandrel rod may be rotated by means of a worm-wheel 17 on the rod and a worm 18. The mandrel rod is moved longitudinally by means of a hydraulic piston 27.

Abstract: <PICT:0393586/III/1> <PICT:0393586/III/2> <PICT:0393586/III/3> Valve apparatus for use in adsorption and other apparatus for drying and purifying air &c. wherein the air or gases are controlled under low pressure differences comprises a circular casing, such as 15, Fig. 1, having spaced lateral ports, as 18, 19, and an axial passage, as 15, 17, in combination with a resilient split rotary sleeve 20, Figs. 1 and 3, having open ends and a lateral port 23 controlling the casing ports in turn.  The forward edge of the split sleeve is driven by a radial arm 21 from the spindle 22, and the port 23 is cut in from the trailing edge 26.  In Fig. 1 upper and lower valves are shown connected to a lagged cylindrical adsorption chamber 11 containing adsorbent material 13, such as silica gel, resting on a screen 12. Air to be dried passes from pipe 34 through the inlet 17 of the upper valve down through the material 13, and out through the exit 18 of the lower valve to the dried air outlet pipe 36.  On reversal of the combined valve, by the hand-wheel 33, the activating inlet pipe 35 passes hot gases to the adsorbent material, the gases being discharged through the waste pipe 37.  In another arrangement, shown in Fig. 6, the valves are arranged in pairs 40, 41, &c., as before, and are provided with an axial passage and six radial passages connected to six adsorber chambers 51 arranged annularly, as shown, the adsorbent being disposed on a series of shelves 52, 53, 54 connected by downwardly-inclined partitions.  A p  second set of adsorbers 61 are provided underneath the first.  Air to be treated passes up the central space, through a filter 75, to the wet air valves 41, 63 and thence to the annularly-disposed chambers 51, 61 surrounding the valves, in succession.  The dried air passes away through the valves 59, 66, and headers 76, 78 to vertically-disposed dry air trunks 71, 74.  Meanwhile hot air for activation passes up through the trunks 69, 70, and headers 79, 80, and through the hot-air inlet valves 64, 40 to the adsorber chambers in succession. The waste activation air is discharged through valves 60, 65, headers 81, 82, and trunks 72, 73.  The ports in the activating valves 64, 40 are shorter than those in the adsorption valves 41, 63 so that the period for adsorption is much longer in each chamber than that for activation, the change-over being executed in proper sequence by the steady actuation of the common valve shaft 50.  A further arrangement is shown in which four double valves, horizontally disposed, are arranged between two pairs of adsorber chambers each containing two shelves of material.  The spindles of the four valves are operated simultaneously by worm gearing on a shaft driven by an electric motor.

Abstract: 899,746. Mixing, opening and feeding fibres. WALKER & SMITH (BATLEY) Ltd. Oct. 13, 1958 [Oct. 29, 1957], No. 33720/57. Classes 120(1) and 120(3) Fibrous material is mixed by obtaining a load of different types thereof and gradually feeding it on a travelling surface and compressing the material to condense it as it approaches a chamber wherein the material is mixed by rotary elements. The mixed, loose material is extracted by air suction from the chamber for further processing. In the apparatus shown, requisite percentages of materials are determined by weighing in a pan 19 (of a weighing machine 20) which is rocked periodically, in timed relation with the advance of material through the apparatus, to deposit a predetermined mixed load into a feed hopper the bottom of which is constituted by an endless conveyer 11 whereon the material is advanced and compressed by the action of an inclined endless lattice 12 to a form which passes through an inlet opening 8 into a chamber 1 wherein rods or flails 3 carried on shafts 2 mix the material, the passage of which through the chamber may be assisted by inclined set (not shown) of rods 3. Mixed material, deposited in a well 10, is continuously extracted through a duct 25 by an air suction device 26, driven from the same motor 6 as drives the shafts 2. The material may be forced from outlet 27 of device 26 and along ducting 28 for delivery to a further processing apparatus, e.g. an opening or teasing machine, the feed hopper of which may be of perforate construction which expends the conveying air and allows the material to fall into the apparatus. The conveyer 11 and lattice 12 are driven from an electric motor 13 and mechanism 14 capable of transmitting a variable, slow speed.
